[PATCH] freecwmp: define code as needing GNU features

[Jonas Gorski <jonas.gorski@gmail.com>]

fixes the following build failure:

freecwmpd-external.o: In function `external_download':
openwrt/build_dir/target-i386_uClibc-0.9.33/freecwmp-2012-04-30/bin/../src/cwmp/external.c:260:
 undefined reference to `WIFEXITED'
openwrt/build_dir/target-i386_uClibc-0.9.33/freecwmp-2012-04-30/bin/../src/cwmp/external.c:260:
 undefined reference to `WEXITSTATUS'

I'm not sure whether this should be fixed in the package Makefile or in
freecwmp's Makefile itself, so I chose the easy way and added it to the
package Makefile.
